Rotary Size Grader

The proprietary Rotary Size Grader removes short pieces, nubbins, loose seeds, and snipped ends of vegetables while conveying good product to downstream equipment. The rotary bed consists of a series of pocket rollers, each with a stainless steel shaft and specific combinations of patented rubber rollers and plastic disks that create the pockets. As the pocket rollers rotate, target-size product settles in the pockets and passes through the bed to be discharged under the machine. Good product is conveyed to the end of the machine.
 

The Rotary Size Grader is ideal for small to medium size product to be classified by length or volume. It is used for full line flow, re-grading, and line flow directly from automatic defect removal systems such as Key’s ADR® line for french fries.
